BRIQUE'IPING-MACHINE.

Specification of Letters Patent.

vlll/'ith this general object in view the in vention consists in utilizing a reciprocating plunger in conjunction wit-h a plurality of dividing4 plates which operate 1n a barrel wherein the compacting of the briquets is accomplished.

The invention further consists in the appliances to supply the material for treatment and the aforesaid dividing plates to the machine, and as they are emitted therefromA to segregate such plates from the finished product and successively return the same for a repetition of the operations.

The invention still further consists in the tion 'of the various parts Aof the apparatus, as will be hereinafter described and claimed.

In the drawings, where similar reference characters designate corresponding parts in all of the views, Figure 1 isa longitudinal view partly in vertical section and partly in side elevation of the headend of a machine embodying my invention; Fig. 2 is av vertical sectional view of an intermediate portion and foot end of the device; Fig. 3 'is a plan view of that part of the machine which is illustrated in Fig. l; Fig. 4 is a plan View of the other end which is included in Fig. 2; and Fig.` 5 is a cross sectional view taken through 5 5 of Fig. 4 drawn to an enlarged scale. 4

According to this invent-ion, I employ a barrel with its axis arranged horizontally, or nearly so, and is desirably comprised of a number of sections, 10, 11, 12, and 13, which are rigidly connected by suitable means, such as screw-bolts 14 for uniting the ilanges 14 provided upon the adjoining ends. The sections 16, 11 and 13 are all bored to substantially the Asame diameters, but section 12 is bored -to a .greater diameter. The section .10 which is adjacent tothe head end of the the vothers so; as' to withstand the eater stresses to which it is subjected and 1s further strengthened by a surrounding sleeve machine is made somewhat stronger than,-

15. The other sections are inclosed by tubes.

16 to afford annular spaces 17 for a heatingmedium, such as steam, which is supplied, from a conduit 18, see Fig. 3, leadin from a' source ofsupply, to the cavity 17 formed in said sleeve at the head end vof the barrel, and thence passes through a communicating duct 19 into the adjacent space 17 and so on through communicating ducts 19 and spaces to a discharge pipe 20.

The barrel-section 10 is provided with an opening to receive the material to be operated upon from a hopper 2l and to the front of such opening and to the top of the c barrel-bore is a recess 22 to house the bent end 23 of a vertically slidable gate 23 which is yieldingly pressed downwardly by a spring 24 to close the bore of the barrel when the plunger 25 is retracted, as will be more fully explained hereinafter. The plunger 25 is fitted to the barrel-bore and has one end supported thereby while its forward end may be carried by a cross-head 26 mounted in slide-ways 27 which are rigid upon a base frame 28 iixedly connected to the barrel. Reciprocating motion is imparted to the plunger from any suitable power means as, for example, Huid pressure operating in a steam or hydraulic cylinder, or it may be actuated by the illustrated devices, .comprising a rotary cam 29 wherewith rollers 30 and 31 carried by said cross-head26 are in engagement with the outer and inner peripheral surfaces 29 'and 29, respectively,

of :the cam flange 29". The cam is mounted upon a power driven shaft 32 which is journaled in bearingboxes 33 formed in or rigidly secured to said frame. Set collars 34, 34" are Acarried upon the plunger 25 in adjusted positions and between these collars is a loose sleeve 35 of less length than the distance said collars are spaced apart. Sleeve 35 has laterally extending pins 35 whereupon are rollers 3 6 which are adapted for engagement with the branches 37 of a bifurcated lever-arm 37 which is fulcrumed to a pivot 38 and is provided in its other arm 37 with a slot 37 wherethrough exposed directly below an opening 42 in the bottom of the barrel and likewise in vertical alinement with the gate part 23.

Extending lengthwise of the machine is a trough 43 for the conveyance of the dividerplates 51 b v an endless chain 44 which passes about wheels 45 and 46 disposed in proxim'ityto the opposite ends of the barrel. -Of these wheels 45 may be the driver mounted upon a transverse shaft 47 deriving its` r0- tary motion from any suitable power means as, for example, the cam-shaft 32 through sprocket chain 4S and wheels 49 and 50 mounted upon the respective shafts. At the head end of the trough 43 is a delivery chute 43', sce F ig. 3, down which by the action of gravity,'roll the dividing plates 51 into the path of travel of the block 40. At the rear end, the barrel has connected thereto a spout 52 having its outer end inclined upwardly as at 52 and at a short distance beyond this spout is a lead-way 53 into which the briquets are discharged.

54 is a spider, see Figs. 4 and5, which is mounted for rotation on a spindle 55 and has the ends of its arms formed concave, as at 56, and are arranged to revolve in the gap intermediate the spout 52 and the lead-way 53. Upon each of the spider arms is a stud 57 which is successively engaged in the notch 58 of arm 58 of a bell-crank which is pivoted at 59 and has a bolt 60 eXtendin through the other arm 58 and also throug a flange 2S of the base-frame. A spring 61 is provided on the bolt between an iadjustable nut 60 and said flange for the purpose 0f causing the bell-crank to resilientlyengage the pins as presented.v

The operation of the invention as hereinbefore-disclosed may be described as fol-v lows: Assuming that the material to be compacted into briquets is supplied to the hopper 21 in ample quantity to meet the demand and that the shaft 32 is rotating the cam 29, the cam then with each rotation and through the office of the rollers 3() and 31 in engagement therewith will project theplunger 25 l into the barrel and retract it therefrom to an extent governed by the eccentricity of the cam. In the former of these mot-ions the plunger carries therewith aj dividing plate 51, which was in the preceding retractile motion of the plunger, elevated into the barrel-bore, and the dividing-plate conveys in its advance' a charge of the material deposited into the barrel-bore to beyond lthe admission opening from the hopper 21, When the plunger has traveled to its full extent into. the barrel, the continued rotation of the cam coacts with the roller 31 to withdraw the plunger releasing the gate 23' so that the spring 24 can assert itself and depress the gate to prevent the material falling into the barrel from following the plunger in its retrograde movement. During the retraction of the plunger, it is drawn through the sleeve 35, in opposition to the weight of the block 40 acting through the lever arms 37, until the sleeve is impinged by the collar 34 whereupon the sleeve is compelled to accompanyv the plunger during the remainder of its retractile movement. During the lost motion with respect to the sleeve, that is while the plunger 1s moving therethrough, the referred to lever is unintluenced by Athe latter, but when motion is imparted to the ysleeve the lever is affected to raise the block 40 and elevate a dividing plate 51 which was previously received thereupon from the trough outlet 43. The dividing plate in ascending encounters vthe bent part 23 of the gate 23 to open the passage-way for the advance of `the, dividing plate when projected by the plunger in the next operative lstroke ofthe latter. .In such operative stroke the plunger is moved sutliciently far to dislodge the dividing plate from on top of the block 40 and also to receive the thrust of the gate before the set collar 34 comes in contact with and actuates the'sleeve 35 to allow the controllin lever to lower the block cycles of operation compacts the charges into a series of briquets 62'interposed be-` tween the successively served dividing plates and by being compressed as they are forced toward the delivery end of the barrel they are thereby compacted into formed condition under the action of heat received from the steam about the barrel.

When the briquets `have arrived at the section 12, that with ythe enlarged bore, they expand diametrically'and in the endeavor to resume the smaller diameters necessary to i enter the smaller bore ofthe adjoining section 13 resist the progressive movement of the following briquets and thus furnish retarding force to react against the compressing power delivered by the plunger. v

The briquets as they are ejected from the barrel adhere, according to the binding ingredient employed, more or less to the contacting dividing f plates and to overcome which a bend is provided in the spout 52 for detlecting the line of -briquets and dividing plates so as to disconnect one from another. When a briquet arrives at the extreme end of this spout it passes through the cncave portion of an arm of the spider 54 and into the chute 53, whence it rolls into a storage bin or other receptacle therefor. The divid- 'ing plates 51, however, being of greater weight than the briquets press downwardly upon an arm with sufficient force to overcome the power of the spring 61 so that the bell-crank is caused to yield to release. the then engaged stud and allow the spider to be rotated until the next stud is` caught. in

the notch 58 ofv the bell-crank. In such movement of the spider the affecting dividf ing plate which is deposited in the trough 43 below and isA therein conveyed to the other end wherefrom it rolls laterally through the chute 43 to be elevated in its turn by the block 40 for another service.

`Among .themore notable' advantages of the invention is the subjection of the briquets to a prolonged action thereupon of heat -which facilitates ltheaction of the binder or adhesive components of thematerial, so that the roduct delivered is in condition for use without further processes. From the repetition of pressures exerted upon the briquets while under the influence of heat the components of the briquets are most intimately united to produce a fuel which kis exceptionally high in caloriic value. The quantity of briquets manufactured from a single machine will be in accordance with' the speed at which the plunger is reciprocated and should be in inverse proportion to the length of the barrel, that 1s to say, assuming that the briquets are to be subjected to the iniiuence of the heat for.

a determinate time, it is obvious that the speed at which they can be propelled through the short barrel must be less rapid than with a` longer barrel.
